BeamMonitor BM+

Performing beam diagnostics on unfocused, continuous irradiation of Co2 and solid-state lasers with higher outputs   

The BeamMonitor (BM+) is the new verson of BeamMonitor and now possesses electronics prepared to meet the current and further demands of signal processing. BM+ can quickly and reliably measure the beam parameters, such as the power density distribution. Analysing and documenting the laser parameters makes it possible to optimize the processing procedure or identify an incorrect beam position or lens alignment.

Typical areas of application are:   

  • Laser and system development 
  • Quality assurance in production of laser sources 
  • Simplifies service and maintenance 

Determine Wear and Deviations   

In practice, laser beams are “customized” for specific areas of application using telescopes and adaptive lenses. When this happens, the beam diameter as well as the divergence are changed dynamically. This makes it possible to change the focus dimensions or shift the focus position toward the laser beam axis in systems for laser cutting or laser welding. Here the focus is on “penetration” through the material surface and it is “pushed into” the material for the actual cutting process. 

During laser welding, dynamic adjustments of the laser beam make it possible to cut with one setting and weld with another.

The BM+ is also suitable for use in the field of quality assurance or laser approval: Deterioration on laser lenses is one of the main causes of problems in laser material processing that can reduce the quality of the processing results considerably. Diodes and other solid-state lasers are checked in the collimated range and can, for example, be assessed with relatively little effort.

Easy Operation   

The new PRIMES LaserDiagnosticsSoftware LDS can be used as a graphic interface for operating the BeamMonitor BM+. This software contains a wide variety of tools for analysis, display, and preparation of measurement data, including a report function.

The software has the following standard functions:

  • Beam measurment 
  • Beam position 
  • Measurements: single measurments, series measuremtns (monitor operation), and measurment of development over time(linescan)
  • Displays: isometry, fales colors, contour, line presentation and display of numeric results
  • Data storge in PRIMES format .lpf as well as CSV and export graphic

Measured beam parameters   

  • Beam position   
  • Beam dimension   
  • Beam summerty   
  • Power density distribution  

Diverse models & options 

  • BeamMontior BM+60
  • BeamMonitor BM+100 
  • Optionally available for Co2 or NIR lasers
  • Depend on the beam size & gemontry, available with apertures of 60 or 100 mm

The aperture should be at least 1.4 times the laser beam diameter. This ensures that the intensities on the edges do not come in contact with the BM+ casing, the measuring range is not unnecessarily limited, and/or a distorted measuring is not produced.
